Nervous girl, don't depend on the ER, get to a cardiologist.
If it's a blockage, angiogram is not the worst thing, I had one last June, had two stents inserted, and I feel better than ever.
You should actually ask for a Heart Scan and CAC score. It's a CT scan of the heart and arteries, and it will show if you have blockages, and give you a score for plaque. Mine was 937, off the charts, and I wasted months worrying I was gonna die. Then I completely changed my lifestyle, eating habits, exercise, and I feel great.
Get a full work up by a good cardiologist , then knowing that you are doing everything possible to stay healthy and improve your chances, don't waste a day worrying, you'll never get that day back.
I know it's easier said than done, I worry too, but worrying alone can cause more plaque (not saying you have plaque, you don't really know if you do)
